i have a pair of klipsch f2 towers with a c2 center,i also have a set of ss-1 sorrounds from a earlier set up,does anyone know if these would be ok with f2 and c2 or should i get the s2 surrounds.....the ss-1 are 65hz-20khz with a 2000 crossover and the s2,s are 82hz-23khz with a 2500 crossover ....both sets are 100 watts with a 400 watt peak.The front 3 speakers are a matched set but i was wondering if there was enough difference in the surround sets to be worth putting out another 500 bucks for the s2's....Thanks for any help and ideas
